Release date: 2019-10-10
This release is based on Postgres Pro Enterprise 9.6.15.1 and provides the following improvement:
The expression comparison function has been reworked to fix bugs and improve support in the future.
Depending on your current installation, the upgrade procedure will differ.
To migrate from vanilla PostgreSQL 9.6.x or Postgres Pro Standard, make sure you have installed its latest minor version and then perform a dump/restore using pg_dumpall.
To upgrade from a Postgres Pro Enterprise version
based on the same PostgreSQL major release,
a dump/restore is not required.
It is usually enough to install the new version into the same installation directory.
Once the new binaries are installed, the pgpro_upgrade
script is run automatically to check whether additional setup is required
and complete the upgrade.
Since pg_probackup delivery model changed in
Postgres Pro Enterprise 9.6.12.1, when upgrading from
a lower version on ALT Linux and Debian-based systems, run
apt dist-upgrade (or apt-get dist-upgrade)
to ensure that all new dependencies are handled correctly. On Windows,
you have to run a separate pg_probackup
installer to complete the upgrade.
When upgrading from version 9.6.9.1 or lower, you must run the
REINDEX command to rebuild GiST and SP-GiST indexes.
When upgrading from version 9.6.8.2 or lower,
you must run the REINDEX command for indexes that used
mchar or mvarchar types.
When upgrading from version 9.6.1.2 on RPM-based
Linux distributions, make sure to move the data directory from
pgsql to the pgproee
directory before running the pgpro_upgrade script.
For some Linux distributions, you may be prompted to run pgpro_upgrade manually.
In this case, you must stop the postgres service.
The script must be run on behalf of the user owning the database
(typically postgres) and PGDATA environment variable should be
set to the directory where database resides. Running pgpro_upgrade
as root will result in an error.
This step is not required when upgrading from version 9.6.4.1 or higher.
